Snapshot of a 3D wavefield simulation for the 1964 Alaska
earthquake (Mw 9).
White lines = faults and plate boundaries; green dots =
seismic stations; yellow dots = Fairbanks, Anchorage, Juneau.
The simulation used the code SPECFEM3D_GLOBE
and was performed on the "pacman" cluster
at the Arctic Region
Supercomputing Center at University of Alaska Fairbanks.

a 3D wavefield simulation for a Mw 4.6 earthquake near
Anchorage, Alaska,
showing the strong effects of Cook Inlet basin on the seismic
wavefield.
A = Anchorage, RV = Redoubt volcano, K = Kenai.

3D wavefield simulation for an earthquake in southern
California.
This earthquake was used in the tomographic inversion presented
here.

and Santiago Lombeyda.Alaska is one
of the most seismically active regions on Earth.This shows
earthquakes with Mw >= 4 from 1990-2010.The deeper
earthquakes highlight the subducting Pacific plate.
